The present studies were performed to characterize geographical distribution of genus Cymbidium grown wild in Korea.
The altitudinal distribution of Cymbidium kanran habitats in Mt. Hanla was ranged from 70 to 840 meters above the sea level, and the geographical distribution of Cymbidium sites in Cheju Island was from nearby Tosan-ri, Pyoseon-myeon, Namcheju-gun in the eastern part of the island to the vicinity of Seokwang-ri, Andeok-myeon, Namcheju-gun in the western area of the island. The orchid habitats, however, were found more abundantly in the environs of Seogwipo city where the altitude ranges from 300 to 600 meters.
C. lancifolium, C. javanicum var, aspidistrifolium and C. koran were rarely grown in the southfacing slopes of Mt. Hanla where the elevation ranges from 200 to 500 meters above the sea level. C. nipponicum was observed in the southern part of Korean peninsula, including Seogwipo city area and Seongsan-myeon, Namcheju-gun in Cheju Island, Mt. Duryoon in Cheonlanam-do, and Yangsan-gun and Ochang-gun in Kyeongsangnam-do.
The latitude for the northern limit of C. virescens habitats in Korea ranges up to the vicinity regions of 38 parallel in the peninsula. Geographical distribution of these Cymbidium was found in the southern part of the line linked with Jangsangot in Hwanghae-do, North Korea, Seosan and Cheonan in Chungchungnam-do, Mt. Seokri in Chungchungbuk-do, Mt. Palgong and Andong in Kyeungsangbuk-do, and to Mt. Seolak and Naksansa temple in Yangyang-gun, Kangwondo, South Korea.
